Summary confidence: high
This dataset records 5,268 airplane crashes across 13 columns, mixing dates and times with operator, aircraft type, route, location, and casualty counts (Aboard, Fatalities, Ground). Casualty figures are highly skewed: Aboard averages 27.5 with a median of 13 and a maximum of 644, while Fatalities averages 20.1 with a median of 9 and a max of 583, and Ground deaths are zero in roughly 96% of rows but spike to 2,750 — clear outliers worth investigating. Operator and Type are dominated by a few heavy hitters (Aeroflot and U.S. military operators; Douglas DC-3 alone appears 334 times), suggesting concentration that could bias any aggregate analysis. Note also that Flight # is missing in nearly 80% of rows and Time in 42%, so those fields are weak for filtering. Start by looking at the Fatalities distribution and the top operators and aircraft types.
